I don't think any of the existing shields designed for Arduino would work because of that small gap, so it's a double-edged sword. I'll be able to make my own shields cheap and easy, but won't be able to use any of the existing shields as drop-ins. I'm going to make a thread about it once I get it all sorted out (schematic wise, it actually looks fairly simple) and I'll post all the nitty-gritty details up on there.

Maybe you could use two rows of headers? One with the normal 1/10" (or whatever it is) gap, and another with the weird Arduino gap?

The only problem is that I want to use perfboard for quick and easy prototyping of shields, and as far as I know there no quick easy way to simulate that gap (besides drilling, but then you would probably end up wrecking the entire board and making it much, much more prone to breaking).

But what about placing the two rows of headers side-by-side, and having one set with "proper" spacing. If you don't understand what I mean, I could try drawing it.

BTW, the specific spacing between the GPIO headers is 160mil (on center of pins), instead of 200mil (according to the eagle .brd file for the Leonardo).

John,

For $1.25 you can buy an offset header which are bent so that they mate the perfboard onto an Arduino.

That is way easier and smarter than what I would have ended up doing. I'm still going to build an arduino board anyways, just to do it It's good to know those shields do exist, though, and that they are pretty cheap.

Perhaps it would be a good idea to start a new thread asking about the servo info. That keeps the subjects a little more separated which will help the next person to find the relevant info more easily

Absolutely! I agree, on keeping these topics separately - it makes matters practical. I am an old member of Rc.Groups.com for many years, and remember spending long hours reading a large trail of threads looking for a technical question that would ultimately end up unconclusive. I have spent some great years there and now it has evolved into this - who would have ever known.
